How do container corners be heat treated?

Container angle is an important force component on the container, often subject to stacking, buckle and lifting, complex shape, general casting forming; The traditional heat treatment is using the process (930 degrees C x 3h, water quenching , 680 degrees C, tempering).

Theoretically, it is difficult to form even tissue for low-carbon, low-quenchable container angle parts, and the traditional heat treatment process requires two heating treatments, largae power consumption, thick oxide skin, large processing volume and high production costs.

Simplifying the traditional process of container angle parts into a one-time positive fire treatment, if it can meet the requirements of mechanical performance, will greatly reduce the production cost and create great economic benefits.
